What are the job attribute preferences of physicians and nurses in Türkiye? Evidence from a discrete choice experiment

BACKGROUND

In Türkiye, as in other countries, the maldistribution of the health workforce is a serious concern. Although policymakers have developed various incentive packages, this problem has not been thoroughly addressed yet. Discrete choice experiment (DCE) is a valuable method to provide evidence-based information for these incentive packages to attract healthcare staff for rural jobs. The main aim of this study is to investigate the stated preferences of physicians and nurses when choosing a job region.

METHODS

A labelled DCE was conducted to assess job preferences of physicians and nurses from two hospitals one of which is urban, and the other is in a rural region in Türkiye Job attributes included wage, creche, infrastructure, workload, education opportunity, housing, and career opportunity. Mixed logit model was used to analyse the data.

RESULTS

The strongest attribute associated with job preferences was region (coefficient - 3.06, [SE 0.18]) for physicians (n = 126) and wages (coefficient 1.02, [SE 0.08]) for nurses (n = 218). According to the Willingness to Pay (WTP) calculations, while the physicians claimed 8627 TRY (1,813 $), the nurses claimed 1407 TRY (296 $) in addition to their monthly salaries to accept a rural job.

CONCLUSION

Both financial and non-financial factors did affect the preferences of physicians and nurses. These DCE results provide information for policymakers about what characteristics might increase the motivation of physicians and nurses to work in rural areas in Türkiye.

Serial multiple mediation of treatment adherence and disease activity in the relationship between continuity of care and health outcomes among rheumatoid arthritis patients

OBJECTIVE

To evaluate the effect of continuity of care on health outcomes (quality of life and functionality) in patients with rheumatoid arthritis and to reveal whether treatment adherence and disease activity have a serial multiple mediator role on this relationship.

METHODS

The study was cross-sectional on 440 rheumatoid arthritis patients who applied to a university hospital rheumatology outpatient clinic. Research data were obtained from both the questionnaire method, which is the primary data source, and the patient files, which are the secondary data source. Process analysis was used in the analysis of the data.

RESULTS

It was found that the continuity of care has a direct effect on the quality of life and the functionality. In addition, it is seen that treatment adherence has a single partial mediator role on the relationship between continuity of care and quality of life; It has been determined that treatment adherence and disease activity have both partial single mediation and serial multiple mediation roles on the relationship between continuity of care and functionality.

CONCLUSION

It is thought that these findings will provide clinicians with important data and information in the management of rheumatoid arthritis.

Paranasal Sinus Fungus Ball, Anatomical Variations and Dental Pathologies: Is There Any Relation?

Objective:

The purpose of this study was to investigate the relationship between anatomical variations and the fungus ball (FB), and the association between odontogenic etiologies and the maxillary sinus FB.

Methods:

We analyzed the clinical records of 66 patients who underwent endoscopic sinus surgery for FB. The anatomical variations determined were nasal septal deviation (NSD) and direction, presence of Onodi and Haller cell, concha bullosa and lateral recess of the sphenoid sinus. Further, dental X-ray records were reviewed to detect any possible odontogenic etiologies in patients with maxillary sinus FBs.

Results:

There were 41 female and 25 male patients. Positive fungal culture was found in 60 patients (91%) and the causative fungus was Aspergillus species in all cases. The correlation between NSD and localization of the maxillary sinus FB was statistically significant (p=0.0409). Maxillary sinus FB was more common on the concave side of the NSD. Presence of dental pathologies was significantly associated with maxillary sinus FB compared to the healthy side (p=0.0011). For sphenoid sinus FB, NSD was detected in a similar number for both the affected and unaffected side and there were no significant correlations (p>0.05). However, the relationship between sphenoid sinus FB and presence of lateral recess was significant (p=0.0262).

Conclusion:

Our study revealed that the maxillary sinus FB was more common on the concave side of the deviated septum. Also, dental pathologies or a presence of dental treatment history were associated with maxillary sinus FB.

Risk factors of deaths related to cardiovascular diseases in World Health Organization (WHO) member countries

This study aims to identify the risk factors affecting deaths related to cardiovascular diseases. The research population comprised of 194 World Health Organization (WHO) member countries, but the data analysis was conducted with the data from 152 countries as 42 of them do not have any data on study variables. Multivariable regression analysis was utilised for this study to analyse the effect of factors regarding metabolism, lifestyle, economic, socio-demographic and health system on the cardiovascular diseases related to deaths. As a result of regression analysis, the number of deaths related to cardiovascular diseases increases with the increase in blood pressure (p < .001), blood glucose (p = .032), obesity rate (p < .001), salt consumption (p < .001), GINI index (p = .002) and dependent age ratio (p < .001); the frequency of cardiovascular disease-related deaths is higher in the countries within low (p < .001) and high (p < .001) middle-income levels; yet, the number of deaths based on cardiovascular diseases diminishes with the increase in the number of doctors (p = .005) and health expenditures per capita (p = .044). The research findings are considered to guide the countries in the determination of their steps towards the prevention of deaths related to cardiovascular diseases.

Sphenoid sinus mucosal thickening in patients with non-functioning pituitary adenoma

AIM

The aim of this study was to evaluate magnetic resonance imaging findings of sphenoid sinus (SS), pituitary gland and related structures in patients with non-functioning pituitary adenoma (NFPA) and compare to a control group.

METHODS

This study was conducted in a tertiary referral hospital between January 2018 and July 2020. Sixty-five patients diagnosed with NFPA and age- and gender-matched controls (n = 40) were included.

RESULTS

The average age in the NFPA group was 37.46 ± 11.2 years and in the control group was 41.97 ± 14.88 years, and they did not differ significantly (P = .103). SS mucosal thickness greater than 1 mm was determined in a higher proportion of NFPA (67.7%) than in the control group (12.5%) (P < .001). A mucosal thickness greater than 3 mm was only present in the NFPA group (43.1%). The distance between optic nerves was significantly longer in the NFPA group compared with control (P < .001). There was a strong positive correlation between adenoma volume and distance between the two optic nerves (r = .728, P < .001). Also, there was a moderate positive correlation between adenoma volume and petrous intercarotid distance (ICD) (r = .561, P < .001) and a low positive correlation between adenoma volume and cavernous ICD (r = .408, P < .001).

CONCLUSIONS

The present study showed an association between NFPA and both SS mucosal thickening and increased distance between optic nerves. Also, our study demonstrated that there was a strong positive correlation between adenoma volume and distance between the two optic nerves.

Supraclavicular artery island flap for head and neck reconstruction

BACKGROUND

The ablative surgical resection has a critical importance for achieving better oncological outcomes for patients with head and neck cancer. However, radical surgical resections reveal the reconstruction requirement of complex anatomical structures. Microvascular free flaps have been recommended as a gold standard treatment choice for head and neck reconstruction following definitive oncological surgery. The supraclavicular artery island flap (SCAIF) is a thin and reliable fasciocutaneous pedicled flap that is simple and quick to harvest.

MATERIAL AND METHODS

A total of 19 patients who underwent head and neck reconstruction with SCAIF were included in this study. The SCAIF was used for the reconstruction of oncological defects in 17 patients while it was used for the reconstruction of a skin defect on the lower face following radiotherapy in 1 patient and for cervical open wound (blast injury) closure in 1 patient.

RESULTS

There were neither intraoperative nor postoperative major complications in any patient. The SCAIF has been used successfully in 18 of 19 patients for head and neck reconstructive surgery. Partial necrosis of the skin was detected in 1 patient (5.3%) only, while a total flap failure has not occurred in any patient. The partial skin necrosis was seen in an area of 1.5 cm of the distal end of the flap and was managed conservatively with local wound care. Wound dehiscence has not appeared in the flap donor area in any patient.

CONCLUSION

The SCAIF constitutes a good alternative to free flaps, providing almost equivalent functional results and requiring less operative time and surgical effort.

Hearing Impairment and Audiological Alterations in Euthyroid Hashimoto's Thyroiditis

INTRODUCTION

Hearing loss may be associated with autoimmune diseases, but it was less studied in Hashimoto's thyroiditis (HT). We aimed to evaluate hearing impairment and audiological alterations in adults with euthyroid HT.

METHODS

Adult patients with euthyroid HT (normal thyroid functions, positive antithyroid peroxidase (anti-TPO)/anti-thyroglobulin, and sonographic findings) were compared with controls. We excluded pregnant or older patients (>40 years), those with a history of otological/audiological disease or surgery, otitis media, acoustic trauma, chronic illnesses, use of alcohol, cigarette, medications, rheumatoid factor, antinuclear, antimitochondrial, antiparietal, antineutrophil cytoplasmic, anti-smooth muscle, or antigliadin antibodies, abnormal biochemical or otological findings. Tympanometry which indicates tympanic peak pressure (TPP, daPa), acoustic reflex testing (ART), pure-tone average (PTA), and transient evoked otoacoustic emission (TEOAE) were performed. We grouped the participants according to ART (positive/negative), TEOAE (normal/undetected), and PTA (≤20/>20 decibel).

RESULTS

Air conduction thresholds on the right ear at 500, 4,000, 6,000, and 8,000 Hz, PTA, and the left ear at 250, 4,000, 6,000, and 8,000 Hz were higher in euthyroid HT (n = 36) than in controls (n = 40) (p < 0.05). We found less negative TPP and a higher ratio of negative ART in euthyroid HT (p < 0.05). Euthyroid HT predicted undetected TEOAE and increased hearing threshold on the right ear at 500 and 8,000 Hz (p < 0.001). TEOAE detected audiological abnormality at a higher rate. Anti-TPO was positively correlated with TPP and air conduction thresholds, except the right ear at 8,000 Hz.

DISCUSSION/CONCLUSION

Hearing and audiological tests may be impaired in euthyroid HT. We recommend close monitoring of audiological functions in these patients. TE-OAE more specifically indicates audiological abnormality.

Evaluation of the Availability of Hospital-Based Health Technology Assessment in Public and Private Hospitals in Turkey: Ankara Province Sample

OBJECTIVES

This study aimed to investigate the extent to which hospitals and managers take the hospital-based health technology assessment (HB-HTA) approach into account in their decision-making processes regarding medical device/equipment acquisition.

METHODS

The questionnaire was developed as a data collection tool and administered to a total of 186 administrators from 33 hospitals in Ankara.

RESULTS

All domains of HB-HTA are taken into consideration in both private and public hospitals but more in private hospitals than public hospitals (P<.001). The importance given to the domains of HB-HTA approach varies according to the characteristics of the hospitals and managers. In addition, it was seen that training hospitals were more likely to consider clinical effectiveness, and safety in specialty hospitals was more important. In addition, medical managers focus more on the clinical effectiveness, whereas administrative and financial managers are more concerned with cost/economic effectiveness. Moreover, the organizational aspects dimension of the HB-HTA was taken into account as the working duration of the managers in the health sector increased.

CONCLUSIONS

Hospitals and managers with different characteristics benefit from the domains of the approach at different levels. To contribute to the use of HB-HTA approach in hospitals and to increase awareness, regional initiatives can be undertaken by encouraging hospitals.

The effects of the age of male early life circumcision on sexual functions later in life

Introduction

According to psychoanalytic theory performing circumcision on a boy in phallic phase may aggravate this fear and cause sexual dysfunctions later in life. However this hypothesis is an unverified common-view rather than a scientifically proven conclusion.

Objectives

We hypothesized that being circumcised during phallic phase is not a risk factor for sexual dysfunction. We also took a peak at how the experience of circumcision is being perceived and its psychological effects. Our secondary hypothesis was, sexual dysfunctions are more frequent among men who had a traumatic circumcision experience.

Methods

For this cross-sectional study, a total of 2768 sexually active, circumcised and voluntary men were recruited from 20 different urology outpatient clinics around Turkey.

Results

There was no significant difference for PEDT and IIEF scores between participants who were circumcised at different ages (Graph-1,2). When participants were divided into 3 groups according to their circumcision age in accordance with psychoanalytic theory (before, after and during phallic phase) mean IIEF and PEDT scores did not differ. PEDT scores did not differ either by which emotion the participant describe their experience of circumcision or how vividly he remembered it. However participants who remembered their circumcision experience more vividly and had who describe their circumcision experience with fear/anxiety had a higher IIEF score (Graph-3).

Conclusions

The age of circumcision does not affect the risk of PE. This is one of the very few studies that challenges psychoanalytic theory with a scientific method. Remembering the circumcision experience with fear or anxiety did not increase the risk of sexual dysfunctions.

Determining the factors affecting the technical efficiency scores of public hospitals using different regression methods

Purpose

This study aims to identify the efficiency scores of hospitals affiliated to the Ministry of Health in Turkey between the years of 2010–2015 at provincial level and to reveal the factors that affect the efficiency scores.

Design/methodology/approach

The two-stage data envelopment analysis (DEA) method was used to achieve the study purpose. In the first stage, DEA method based on input-oriented Charnes–Cooper–Rhodes (CCR) model was performed to calculate the efficiency scores of public hospitals at the provincial level between 2010 and 2015, and in the second stage, Tobit regression and linear regression analyses were used to identify whether the efficiency scores of provinces are affected by the input, output and control variables.

Findings

Upon the analysis, the average efficiency scores of 81 provinces by years were found to vary between 0.79 and 0.89. According to both regression analyses, all of the input and output variables were found to have significant effects on the efficiency scores of provinces while only the population of province among the control variables was identified as the factor with an effect on the efficiency scores of provinces (p < 0.05).

Practical implications

The results of this study are thought to guide health policymakers and managers in terms of both determining efficient and inefficient hospitals at the provincial level and revealing which variables should be taken into account in order to increase efficiency.

Originality/value

The study differs from previous studies on the efficiency of hospitals. First, although previous studies were generally descriptive studies to determine the efficiency level of hospitals, this study is an analytical study that tries also to show the factors affecting the efficiency of hospitals. In addition, while examining the effect of input and output variables on efficiency scores, control variables were also included in the study.

Drainless resection of the submandibular gland with facial vessel preservation: A comparative study

OBJECTIVE

Resection of the submandibular gland (SMG) is a common surgery and many surgeons leave a drainage system in the surgical field. However, surgical drain may increase risk of complication and related prolonged hospitalization time. The purpose of this study was to investigate the safety of SMG resection without any surgical drainage system.

METHODS

This retrospective trial on SMG surgery was conducted between 2016 and 2019. Patients were assigned into one of two main groups: surgical drain (+) (n=20) and surgical drain (-) (n=17). All surgical procedures were done via a standardized surgical technique. Facial vessels were dissected and only glandular branches were ligated. Also, non-identification method was applied for marginal mandibular nerve (MMN) protecting. In surgical drain (-) group, before the wound closure, oxidized regenerated cellulose (ORC) was placed in the surgical field. Moreover, a closed suction drain was inserted in surgical drain (+) group.

RESULTS

A total of 37 SMG resections were performed: 15 patients had sialolithiasis, 14 patients had pleomorphic adenoma and 8 patients had chronic sialadenitis. There were 20 women (54%) and 17 men (46%), with an age range of 23-70 years. No major complications were observed in surgical drain (-) group. There were two cases with minor complications. One patient (5.8%) occurred transient paralysis of the MMN. Other patient developed seroma and it was easily managed with repeated punctures. ORC related allergic reaction or adverse incident were not detected in any of the patients. On the other hand, in surgical drain (+) group, 2 patients (10%) developed a hematoma on the first postoperative day and local wound infection was detected in 4 patients (20%). We found that the surgical drain usage was related to prolonged hospitalization, worse wound healing and problems with scarring.

CONCLUSION

Our findings provide evidence for the safe drainless resection of the SMG using ORC. It may be possible to prevent all of these undesirable conditions by a surgery which performed without drain insertion.

Atypical Metastasis to the Head and Neck Region: An Analysis of 11 Patients

Objective

We present 11 patients with distant metastases to the head and neck from an infraclavicularly located primary tumor and discuss the management strategies including the clinical presentation, treatment modalities, and prognosis.

Methods

The retrospective data of the pathology reports and operation notes of 1239 patients who had undergone any kind of oncological surgical intervention between 2005 and 2017 were analyzed. All of the 11 patients included in the study were evaluated in our department's tumor board, and all patients with an operable lesion had undergone surgery. Inoperable patients were treated with chemotherapy and/or radiotherapy.

Results

The average age of the patients was 64.3 (48-88) years. Primary tumors were located in the lung (2), breast (2), ovary (2), prostate (2), kidney (1), and colon (1) and the primary lesion could not be determined in one patient. The most common symptom was newly occurred painless swelling (9/11, 81.8%) at the metastatic site. Four patients without any other distant metastases were operated. Of these four patients, two died during follow-up due to systemic disease, and the other two are alive and disease-free. Three of the seven inoperable patients were treated with chemotherapy and the other four with radiotherapy. The prognosis of this group was worse.

Conclusion

Although metastasis to the head and neck is not common, it is vital to keep in mind while approaching a patient with a lesion at the head and neck region especially if there is a history of lung, breast, and genitourinary cancers. Despite the poor prognosis, diminishing the tumor burden would increase the treatment success.

Prognostic factors in head and neck mucosal malignant melanoma

OBJECTIVE

Primary mucosal malignant melanoma of the head and neck (HN-PMMM) is an aggressive and uncommon neoplasm. Herein, we present a series of 33 patients and the results of treatment, and aimed to determine prognostic factors in HN-PMMM.

METHODS

Patients who were diagnosed as having HN-PMMM in our reference hospital, between 2005 and 2014 were evaluated. Thirty-three of these patients who had follow-up data were included. Surgical margin status was extracted from the original pathology reports. Archived materials were retrieved for the histopathologic findings: ulceration, necrosis, lymphovascular invasion, perineural invasion, pigmentation, and presence of an in situ component. Mitotic activity was evaluated using phosphohistone H3 (PHH3) immunohistochemical staining.

RESULTS

We found an association of PHH3 mitotic activity with overall survival in a univariate analysis and to our knowledge, this is the first report among the available case series of HN-PMMM to evaluate mitotic activity using immunohistochemical staining. We also investigated the relationship between multicentricity and locoregional recurrence, which the authors believe is also a first.

CONCLUSION

PHH3 mitotic activity can be used a prognostic factor for head and neck mucosal malignant melanoma.

Cost-effectiveness analysis of pemetrexed and gemcitabine treatment for advanced nonsmall cell lung cancer in Turkey

BACKGROUND/AIM

The purpose of the study is to determine the cost-effectiveness of the chemotherapy medications that contain gemcitabine and pemetrexed, which are used in the treatment of advanced nonsmall cell lung cancer (NSCLC).

MATERIALS AND METHODS

The study evaluated the effectiveness and cost of platinum-based pemetrexed and gemcitabine treatments as the first-line treatment of advanced NSCLC with the use of the Markov model, and from the perspective of the Social Security Institution. NSCLC costs calculated on the basis of experts' opinions and the effectiveness values calculated by administering the EQ-5D questionnaire to the patients were analyzed. All direct medical costs were included in the model.

RESULTS

While the life-long cost of gemcitabine/cisplatin treatment was determined to be 10,347.45 Turkish lira per patient, it was determined as 17,783.34 for pemetrexed/cisplatin treatment. The incremental cost of pemetrexed/cisplatin treatment is 220,754 per quality-adjusted life year.

CONCLUSION

Although there is no official threshold value in Turkey, due to the fact that the incremental cost effectiveness ratio exceeds the threshold value calculated on the basis of GDP per capita, it is understood that pemetrexed/cisplatin is not cost-effective in the first-line treatment of advanced NSCLC.
