Introduction

The nursing process is the work method used in nursing and permits, through research, logical analysis and analytic reasoning, the development and application of technical, interpersonal or relational and communication care. It involves five steps: assessment, diagnosis, planning, execution and, finally, evaluation^{( 1}1 . Alfaro-Lefevre R. Applying nursing process: the foundation for clinical reasoning. Philadelphia: Lippincott; 2014. 3 p. ⁾.

Its creation dates back to the 1950-1960's in the United States of America and Canada^{( 2}2 . De la Cuesta C. The Nursing Process: from development to implementation. J Adv Nurs. 1983;8(5):365-71. ⁾. In the initial years, it is mainly discussed and developed in teaching. In the 1970's, it is extended to clinical practice (professional practice) in those countries and continues developing. The establishment of the nursing diagnoses and NIC-NOC terminologies are steps that stand out in this development. Nowadays, the nursing process is used at health centers all over the world^{( 3}3 .

In the same decades as the creation and the implementation of the nursing process, models and theories are established that serve as a guide for professional nursing practice^{( 5}5 . Raile M, Marriner A. Nursing theorists and their work. 7th. ed. New York: Mosby/Elsevier; 2010. 3-15 p. ⁾. While the nursing process is a method to organize professional practice, the nursing models and theories are a framework to understand and give meaning to this professional practice, which guarantees a strict practice based on personal experience and on the scientific and philosophical premises each theorist contributes. Therefore, one should depart from general philosophical and scientific elements that will transform into concrete and unique elements, which will serve to define the empirical and operative elements of each conceptual model. In that sense, the nursing guides or models used condition the practice, which rests on the theoretical foundations each model contains and which the nurses identify with, accepting that the clients and their own reality are conditioned by the underlying theoretical base^{( 6}6  6.

In general, one might say that the nursing models and theories help to identify the objectives and practice means each person is provided with^{( 7}7 . Meleis A. Theoretical nursing development and progress. 5th. ed. Philadelphia: Lippincott-Willians & Wilkins; 2012. 10 p. ⁾. To give an example, when adopting the Henderson model, the nurses accept the proposal to satisfy the patients' needs and aim to generate the independence of each person. If they prefer Orem's model, they will aim to maximize the clients' self-care skills^{( 6}6  6. Durán de Villalobos M. Marco epistemológico de la enfermería. Aquichan.

Later, without reaching the point of being models or theories, different nursing assessment structures are published, including Carpenito's bifocal structure^{( 8}8 . Carpenito LJ. Nursing diagnosis: Application to clinical practice. 14th. ed. Philadelphia: Lippincott-Willians & Wilkins; 2013. ⁾ and Gordon's conceptual structure^{( 9}9 . Gordon M. Manual of nursing diagnosis. 12th. ed. London: Jones and Bartlett Publishers International; 2010. ⁾. The bifocal structure Carpenito introduced in 1983 is a model in which the clinical situations are identified in which the nurse intervenes, making reference to independent nursing work and interdependent or collaborative work. Gordon's conceptual structure serves as a general reference framework to assess each person through the proposed Functional Health Patterns. After obtaining Gordon's permission and after being modified by NANDA International's taxonomy committee, the NANDA accepted this structure in April 1998^{( 10}10 . NANDA-International. Diagnósticos enfermeros. Definiciones y clasificación 2012-2014. Barcelona: Elsevier; 2013. 49 p. ⁾.

Few studies^(11-12) have been found in the Spanish context that contribute with numerical data about the nursing models and structures used in the application of the nursing method. These studies are not monographs about the theme and do not indicate concrete start dates.

The objective in this research is to study what nursing models and structures have been used to implement the nursing process at the public and private centers in the health area Gipuzkoa (Basque Country). The results will reveal the evolution in the nursing work mode in Gipuzkoa and the past and current presence of the nursing models and structures in the nursing method.

Method

A retrospective study was undertaken about the nursing records used at the public and private centers in the health area Gipuzkoa, one of the three health areas in the Basque Country.

In total, 158 centers were studied: 137 public (all public centers) and 21 private (all centers with a staff of 10 or more nursing professionals). At these 158 centers, 2667 nursing professionals work (2103 at the public centers and 564 at the private centers), which correspond to 90% of all professionals working in clinical practice in Gipuzkoa.

The nursing records were obtained or visualized after getting authorization from the management of the involved centers, and after interviewing the professionals responsible for these records. The anonymity of the centers was preserved in the publication of the data.

The Research Ethics Committee at the Universidad del País Vasco - Euskal Herriko Unibertsitatea (UPV-EHU) started its activities in 2010. The data for this study were collected between January and December 2009, which is why the assessment of this committee was not possible.

The following data were collected for each center:

Quantitative analysis was applied to the data, using descriptive statistics.

Results

In Table 1, the centers studied are shown, as well as the number of nursing professionals, the year the application of the nursing process (NP) started, the nursing model or assessment structure used in the application of the nursing process and the year this nursing model or assessment structure started to be used. When the cell is empty, this means that the above are not used at the center. The number of nursing professionals working at each center reveals its size.

According to the figures in Table 1, besides some exception, the use of the nursing process starts in 1990 and is generalized in the first decade of the 21^st century. Nowadays, at 155 (98%) out of the 158 centers studied, the nursing process is applied. It is applied at all public centers and 18 out of 21 private centers. The details of this start are available for one public center and 18 out of 21 private centers. These details are available in a previously published retrospective study^{( 15}15 . Huitzi-Egilegor JX, Elorza-Puyadena MI, Urkia-Etxabe JM, Esnaola-Herrero MV, Asurabarrena-Iraola C. Retrospective study of the implementation of the nursing process in a health area. Rev. Latino-Am. Enfermagem. 2013;21(5):1049-53. ⁾, and the details of the current use (the use of the nursing diagnoses, the NIC-NOC terminologies and the standardized care plans) in an also published cross-sectional study^{( 12}12 . Huitzi-Egilegor JX, Elorza-Puyadena MI, Urkia-Etxabe JM, Zubero-Linaza J, Zupiria-Gorostidi X. Use of the nursing process at public and private centers in a health area. Rev. Latino-Am. Enfermagem. 2012;20(5):903-8. ⁾.

At 127 (82%) out of the 155 centers that apply the nursing process, Henderson's model is used; at six (4%) Carpenito's bifocal structure is used; at 17 (11%) Gordon's conceptual structure and, at one, the RAI-NH 2.0 structure (Resident Assessment Instrument Nursing Home 2.0). At the remaining four centers, the nursing process is applied without the support of any model or assessment structure, with records being elaborated according to the particular criterion of the nursing professionals at each center.

Carpenito's bifocal structure, also known as the bifocal model of clinical practice, is an assessment structure that proposes the use of a nursing model to recollect that data that permit obtaining the client's nursing diagnoses and the use of the body system assessment structure to collect the data that permit obtaining the interdependent problems or the client's cooperation. At the public specialized care centers and the psychiatry service of hospital No. 1 studied, Carpenito's bifocal structure has been implemented as follows: Henderson's model has been used to collect the data that permit reaching the client's nursing diagnoses, and the body system assessment structure has been used to collect the data that permit reaching the client's interdependent problems. Therefore, keeping in mind that the centers that use Carpenito's bifocal structure are applying Henderson's model, when adding up the 127 centers where Henderson's model is used and the six centers where Carpenito's bifocal structure is applied, today, among the 155 centers that apply the nursing process, at 133 (86%), Henderson's model is used.

In terms of the number of nursing professionals, at the centers where the nursing process is applied with the sole use of Henderson's model, 578 professionals are active (24% of all professionals who work at the 155 centers where the nursing process is applied); at the centers where Carpenito's bifocal structure is used, 1545 (65%); at the centers where Gordon's conceptual structure is used, 101 (4%) and, at the center where the RAI-NH 2.0 structure is used, 10 (0.4%). When adding up the 578 nursing professionals who work at the centers where the nursing process is applied using Henderson's model and the 1545 professionals who work at the centers where the nursing process is applied using Carpenito's bifocal structure, today, 2123 (89%) of the professionals work at centers that use Henderson's model.

Concerning the start year of the model or structure, it should be highlighted that, at some centers, the selected model or structure has varied over time: at the public specialized care center or at the psychiatry service of public hospital No. 1, in 1990-1994, Henderson's nursing model was used and, as from 1994, Carpenito's bifocal structure; at private mental health hospital No. 2, in 1998-2005, Henderson's nursing model was used and, as from 2005, Gordon's conceptual structure.

When considering the activity area, it is observed that Henderson's nursing model is used in all areas; the bifocal structure is mainly used in the specialized care area; Gordon's conceptual structure is mainly used in the mental health area and the RAI-NH 2.0 structure in geriatrics.

Discussion

The results show that, in Gipuzkoa, Henderson's model has been the most used in the implementation of the nursing process. That is in accordance with the authors who refer that Henderson's model is one of the most well-known and globally used models^{( 5}5 . Raile M, Marriner A. Nursing theorists and their work. 7th. ed. New York: Mosby/Elsevier; 2010. 3-15 p. ^{, 16}16 . Luis MT, Navarro MV, Fernández C. De la teoría a la práctica: el pensamiento de Virginia Henderson en el Siglo XXI. 3th. ed. Barcelona: Masson; 2005. 46 p. ⁾.

The usage figures obtained in this study, superior to 80% in the case of Henderson's model, is higher than the figures obtained in other similar studies. In a study undertaken in Spain, it is affirmed that, in primary care, 35% of the centers use Henderson's model, which is the only one used^{( 11}11 . Izquierdo JM, Pérez MB, Ramírez FJ, Serrano I, Torres MD, Conde G. Implantación del proceso enfermero. Rol Enferm. 2002;25(7-8):488-93. ⁾. In a study undertaken in Canada, it was found that only 25.5% of the centers use a nursing model to apply the nursing process^{( 17}17 . Simpson J, Taylor D. Reality check. Do conceptual models of nursing work today? Can Nurse. 2002 Feb ;98(2):24-6. ⁾. The study does not specify what nursing models are used. In another study developed in Poland, it is concluded that, in that country's clinical practice, the ideas and theories of Nightingale, Orem and Henderson are used, but the study does not quantify this use per centers^{( 18}18 . Zarzycka D, Dobrowolska B, Slusarska B, Wronska I, Cuber T, Pajnkihar M. Theoretical foundations of nursing practice in Poland. Nurs Sci Q. 2013;26(1):80-4. ⁾.

In general, in Gipuzkoa, the nursing process is applied under the influence of a nursing model or theory. Exceptions are the centers that apply the nursing process using Gordon's conceptual structure, the RAI-NH 2.0^{( 19}19 . Morris JN, Hawes C, Fries BE, Phillips CD, Mor V, Katz S,et al. Designing the national resident assessment instrument for nursing homes. Gerontologist. 1990;30(3):293-307. ⁾ structure or with records made in line with the center professionals' private criterion. It should be kept in mind that Gordon's conceptual structure and the RAI-NH 2.0 structure are not actually nursing models, but nursing assessment structures.

In view of the above, those centers should be focused on which, over time, have varied their choice of the model or assessment structure. These variations have affected 1567 nursing professionals (66% of all professionals who work at the 155 centers who apply the nursing process), and are related either to replacing Henderson's model by an assessment structure or to complementing Henderson's model with Carpenito's bifocal structure. It seems that, at these centers, Henderson's model alone was not sufficient for the correct assessment of the patient-client, and that something more or something different was required. Therefore, in Gipuzkoa, the trend is observed to complement or replace Henderson's model by nursing assessment structures.

This trend appears to confirm those authors who alert to the problems that can emerge if the selected model is not used correctly or who indicate difficulties when combining the nursing model with the incorporation of novelties (the nursing diagnoses, the NIC-NOC terminologies) related to the nursing process^{( 20}20 . Kalisch BJ, Landstrom GL, Hinshaw AS. Missed nursing care: a concept analysis. J Adv Nurs. 2009;65(7):1509-17. ^{- 21}21 . Reyes J, Jara P, Merino JM. Adherencia de las enfermeras/os a utilizar un modelo teórico como base de la valoración de enfermería. Cienc Enferm. [Internet] . jun 2007 [acesso 16 maio 2014]; 13(1):45-57.

http://dx.doi.org/10.4067/S0717-95532007... ⁾.

Concerning the activity area, as mentioned, Gordon's conceptual structure is mainly used in the mental sector. This can be due to the fact that the school in the Basque Country that offers the programs to obtain the degree of mental health nursing specialist has selected this structure.

As regards the geriatric area, it should be observed that, at the public as well as the private centers, in the nursing assessment records, a paragraph was found in which the patients' ability to accomplish the activities of daily living is assessed. This term "activities of daily living" reminds of the term "activities of living" in the nursing model by Roper-Logan-Tierney^{( 22}22 . Roper N, Logan WW, Tierney AJ. The Roper-Logan-Tierney model of nursing: based on activities of living. 3th. ed. Edinburgh: Churchill Livingstone; 2009. ⁾ but, in the records studied, the 12 activities of living this model proposes are not assessed, but only those activities that propose the indices used to measure the autonomy in the accomplishment of the activities of daily living (Katz, Barthel and Lawton indices). That is the reason why it was not considered that this nursing model is applied.

Finally, it is noteworthy that, at almost all public centers in the same area, the selected assessment model or structure coincides and is simultaneous over time. At the private centers, on the other hand, there are differences in the choice of the model or assessment structure as well as in the start date. That is so because, at the public centers, the management of each area, which drives the changes, is unified. The management at the private centers, on the other hand, is independent, without any connections among them.

Conclusions

These study results show that, in Gipuzkoa, Henderson's model has been the most used in the implementation of the nursing process.

Over time, a trend is observed to complement or replace Henderson's model by nursing assessment structures.

Finally, this study reveals that, at the public centers in the same area, the nursing model or assessment structure almost always coincides, which is not the case at the private centers.
